256GB DDR5 ECC RDIMM Kit for Thinkmate Workstations

This 256GB kit contains four 64GB DDR5 modules built for the Thinkmate VSX-R5-760RTP7 workstation. Each module is a registered ECC RDIMM that provides error correction for data integrity in server environments. The kit targets IT professionals who need validated, high-capacity memory for mission-critical workloads.

Capacity headroom at 4800 MT/s with CL40 latency

Four ranks of 2Rx4 density deliver 256GB total, giving ample headroom for large datasets, virtualisation and in-memory databases. The registered buffer reduces electrical load on the memory controller, allowing the full population of slots at rated speed. Workloads that exceed 256GB or require lower latency than CL40 will need a different configuration.

Registered ECC RDIMM form factor with 1.1V operation

The 288-pin DDR5 RDIMM interface and registered ECC design are the single specification that determines compatibility; only systems that accept DDR5 registered ECC modules can use this kit. It operates at 1.1V standard voltage and carries the PC5-38400 speed rating. Desktop boards or platforms requiring unbuffered memory cannot accept these modules.

Questions about this item

Will the 288-pin DDR5 RDIMM modules work in the existing Thinkmate VSX-R5-760RTP7 memory slots?

Yes, this kit is built for the Thinkmate VSX-R5-760RTP7 and uses 288-pin DDR5 RDIMM modules that match the workstation's registered DIMM slots.

How can I confirm the 256 GB kit is running at 4800 MT/s with CL40 latency after installation?

Check the BIOS or UEFI memory information screen; it should report 4800 MT/s speed, CL40 CAS latency and 1.10 V operating voltage for each 64 GB module.

Does the package include only the four 64 GB modules or are extra items like heat spreaders supplied?

The box contains the four 64 GB DDR5 4800 ECC RDIMM modules only; no heat spreaders or additional accessories are included.
